So a few days ago I was in my lab as always…
when I start hearing this pop pop pop pop sound…
I didn’t know what It was till today…
No power necessary…. these spare caps blew by themselves…
Yay for Truth branded caps!
My lab doesn’t get cold and isn’t too dry… what gives?
Anyone have any brands they know are good and wont pop before/ while you use them

This is just what cheap electrolytic capacitors do. They are simply built improperly and like to commit suicide.
Buy a decent brand from a reputable source like Farnell, Digikey, Mouser, Allied Electronics etc.

You’ll find everything you need to know in here:http://en.wikipedia.org/wiki/Capacitor_plague
Stick with a known brand. For replacements in working equipment I always go with premium options from premium brands … I have replaced lots of motherboard capacitors with Sanyo and Panasonic brand capacitors over the years.
It’s a simple fact of life that the big brands have more to lose if they screw up.

Two thoughts:
1) It could be a chemical reaction producing gas – improper cleaning between production steps, etc.
2) The legs of the capacitors do act as antennas – if a strong enough RF signal is nearby, then it could be producing a charge across the cpacitor.

Seriously, man? RF won’t charge them up, as you have no rectification-element. The internal losses in the cap will be bigger than the few uW you /could/ pick up.
Also, as long as the leads is pointing the same way, not much antenna action there…
